We're experiencing seriously delayed speeds when direct database connecting to an SDE/SQL raster catalog from ArcGIS 10.3.1. Prior to 10.3.1 we were using 10.1 and did not have any issues beyond a short delay given the size of the dataset; however, we're now waiting upwards of 10-15 minutes to establish a connection. After connecting everything seems to be fine...it's just the initial communication.
We're in the process of converting the imagery to a mosaic dataset to be served via an image service; however, we'd like to find an interim solution for the existing connections that doesn't take 10+ minutes to connect. I'm not even sure what tools are at my disposal to troubleshoot the issue.
